We've seen over the last few years how quickly players from Cuba are able to make an impact at the major league level. Jose Abreu, Yoenis Cespedes, Aroldis Chapman, Jose Fernandez and Yasiel Puig have all developed into stars, and they hardly needed any time in the minors.

Castillo is thought to be the newest player ready to follow that trend. According to sources cited by CBS Sports' Jon Heyman, the 27-year-old has plans of making his major league debut in 2014.

Bostonwon't need him in order to compete for the pennant this year, but it appears they've added a major piece for 2015 and beyond. If Castillo can punish pitchers the first time around like Puig or Abreu did, he'll give this team a massive lift.

Offensively, he's not expected to provide the same kind of power as Abreu or Cespedes. However, he's a line-drive hitter who boasts lightning speed. You can see a little bit of that in the video produced by his agency, Roc Nation Sports:

Looks like Roc Nation Sports put out a new video of Rusney Castillo from his Miami showcase. Love the special effects http://t.co/6D3Q3ryxFu

Defensively, Castillo's most likely landing spot is in center field, although during his recruitment process there were teams that viewed him as a middle infielder. There are slight concerns about his arm, but Baseball America's Ben Badler, via MassLive.com's Jason Mastrodonato, doesn't see that as a problem:

I don’t see that as a major hitch. There aren’t a ton of center fielders that are really playing with above-average arms right now. You look at his speed, jumps and reads he gets off the bat, there’s going to be plenty of range for him to play center field.

It's difficult to project exactly how Castillo will translate to the majors, but his talent is unmistakable. At the very least, he has the speed to cause mayhem on the basepaths and cover a lot of ground in the outfield.

His upside has him drawing comparisons to reigning NL MVP Andrew McCutchen, and even if that's a stretch, it's clear John Farrelland his team just improved both the present and the future.
